Superconductivity induced by structural reorganization in the electron-doped cuprate NdCeCuO
Anita Guarino, Carmine Autieri, Pasquale Marra +4
Electron-doped and hole-doped superconducting cuprates exhibit a symmetric phase diagram as a function of doping. This symmetry is however only approximate. Indeed, electron-doped…
Dimensionality of the superconductivity in the transition metal pnictide WP
Angela Nigro, Giuseppe Cuono, Pasquale Marra +9
We report theoretical and experimental results on the transition metal pnictide WP. The theoretical outcomes based on tight-binding calculations and density functional theory indic…
Geometry Effects on Switching Currents in Superconducting Ultra Thin Films
A. Leo, N. Martucciello, A. Guarino +6
Vortex dynamics is strongly connected with the mechanisms responsible for the photon detection of superconducting devices. Indeed, the local suppression of superconductivity by pho…
Angular dependence of vortex instability in a layered superconductor: the case study of Fe(Se,Te) material
Gaia Grimaldi, Antonio Leo, Angela Nigro +4
Anisotropy effects on flux pinning and flux flow are strongly effective in cuprate as well as iron-based superconductors due to their intrinsically layered crystallographic structu…
Quenching current by flux-flow instability in iron-chalcogenides thin films
Antonio Leo, Gaia Grimaldi, Anita Guarino +8
The stability against quench is one of the main issue to be pursued in a superconducting material which should be able to perform at very high levels of current densities. Here we…
Disorder-sensitive pump-probe measurements on NdCeCuO films
Adolfo Avella, Carmela Buonavolontà, Anita Guarino +6
We find an unambiguous relationship between disorder-driven features in the temperature dependence of the resistance and the behavior, as functions of the temperature, of the param…
Magneto-transport measurements on NdCeCuO thin films
Anita Guarino, Antonio Leo, Francesco Avitabile +6
NdCeCuO (NCCO) epitaxial thin films have been deposited on (100) SrTiO substrates by DC sputtering technique in different atmosphere. The as-grown samples…
Stability mechanisms of high current transport in iron-chalcogenides superconducting films
Antonio Leo, Gaia Grimaldi, Pasquale Marra +8
The improvement in the fabrication techniques of iron-based superconductors have made these materials real competitors of high temperature superconductors and MgB. In particula…
Competition between intrinsic and extrinsic effects in the quenching of the superconducting state in FeSeTe thin films
Antonio Leo, Pasquale Marra, Gaia Grimaldi +6
We report the first experimental observation of the quenching of the superconducting state in current-voltage characteristics of an iron-based superconductor, namely, in FeSeTe thi…
Quasiparticle scattering time in superconducting films: from dirty to clean limit
A. Leo, G. Grimaldi, R. Citro +3
We study the quasiparticle energy relaxation processes in superconducting Nb films of different thicknesses corresponding to different electron mean free paths in a state far from…
